2 Claims. 1

This invention relates to a pedal lift gate that opens upwardly.

It is the object of my invention to provide a gate of simple andinexpensive construction that will open with a slight pressure of thefoot upon a pedal.

Another object of my invention is to provide a device that is balancedto such precision that very little efiort is required for opening orclosing.

Another object of my invention is to provide a gate that will open orclose from either side without the operator moving from his place uponthe ground.

Another object of my invention is to provide a gate of unusually longlife due to being suspended in an upright position when in openposition.

Another object of my invention is to provide a device to which existinggates may be attached for th s novel way of operation.

Other and further features and objects of the invention will be moreapparent to those skilled in the art upon a consideration of theaccompanying drawings and following specifications, wherein is discloseda single exemplary embodiment of the invention with the understanding,however, that such changes may be made therein as fall within the scopeof the appended claims, without departing from the spirit of theinvention.

Figure 1 is a view in perspective of my device in closed position andshows in particular, the balance weight, and suspending lever.

Figure 2 is a perspective view of the gate in open position and showsthe balance weight floating adjacent to the ground.

Figure 3 is an enlarged view looking from the top showing the generalframe arrangement and illustrating in particular the pivoted gatesupporting member and pedal cross-shaft.

Figure 4 is an enlarged close-up view of the locking arrangement.

Referring now to the drawings a preferred embodiment of my inventionincludes a gate indicated generally at H), a frame A and an opening andclosing mechanism at H.

The closing mechanism frame IA is composed of side members l2 and 2A,auxiliary member l3 and cross members l4 and MA. The gate I is securedto member 5 at l6 and is braced by H. Member I5 is the main support ofthe gate and is pivoted in the frame members l2 and 2A at pointsadjacent their forward ends indicated at l8 and IBA. Member IE to whichthe pedal levers 20 and 20A are secured is pivoted arm 28 is alsosecured to member 26 at 29 as shown in Figure 3 to form a compoundlever, a lever arm 30 is attached to cross bar |5 at 3| and a linkmember 32 is pivotally connected to levers 28 and 3|] at 30A. A weight33 is suspended from lever 25 at 34 and a compensating spring 35 ispivotally attached to levers 28 and 30 at 28A to obtain a balance inopening and closing. A connecting member 36 is pivotally attached tolever 25 at 31 and to the pedal member 20 at 38 as shown by a dotteddirectional line in Figure 3.

Attached to the side frame members l2 and, |2A and extending verticallyare members 39 and 39A braced by members 40. Pivotally attached to thevertical members 39 and 39A are angular shaped handles 4| and MA theirouter ends 43 being adapted to link with cooperating members 20 and 20Aby means of members 43A pivotally attached at 42 and 42A. A lockingarrangement shown in Figure 4 and indicated at 44 and 44A is attached tothe upper extremities of members 39 and 39A and operates from eitherside of the gate by moving one of the pins 44 or 44A into an opening inthe gate shown at 45, while an additional opening 46 is provided so thatthe outer end of the gate may be locked in a raised position to permithogs or other small stock to pass under. Posts between which the outerend of the gate ll] rests are shown at 41. Foot contact members areattached to the free ends of the pedal levers 20 and 20A as shown at 48and 48A. Where references are made as to members being attached orsecured to other members it is understood that any of customary methodsmay be used for this purpose.

In use, the operator may be on either side of the gate as duplicatecontrols are provided. To raise, one places his foot on pedal 48 andpushes downward; this causes a pull on the connecting link 36, arearwardly movement of lever 28 and cooperating lever 30, a lowering ofthe balance weight 33, an inward movement of the handles 4| and thesubsequent raising of the gate II! to an upright position and theexpansion of the compensating spring 35. To lower, one grasps handle 4|and pulls forward, being connected to pedal levers 20 as shown at 42 and43, this effects a 3 reverse action and raises the pedals 48 and lowersgate II] to closed position. To lock gate in position one moves slidingpin 44 into place.

I claim as my invention:

1. In a pedal lift device, the combination of a frame composed of crossmembers and parallel side members secured together, a main shaft crossmember pivoted in the parallel side members at points adjacent to theirforward ends, ,a gate secured to the pivoted shaft, another-cross shaftpivoted in the parallel side frame members at points adjacent to theirrearward ends, a pair of pedal levers attached thereto, a pair ofupright frame members supporting a pivoted compound lever, a weightattached to the elongated upper '1 arm of the lever, an operatingleversecured to the main cross shaft at a point" adjacent to the" gate; aconnecting member between the operatinglever 2. The combination, with aframe, of a gate secured to a lever member pivotally attached to membersplaced adjacent to the handles and v adapted to fit within apertures inthe gate, substantially as described.
